This is driving me completely nuts and is making Vista a lot more irritating than it has to be.

For some reason, all of the games I have played in Vista have mouse acceleration enabled, even though its turned off in setpoint and in windows.

What this means is if I move the mouse 3 inches slowly I can do a full turn in a first person shooter. If I move the mouse 3 inches quickly it will do 1.5 or 2 turns. This makes it nearly impossible to aim accurately, especially since I've been playing games with acceleration off for as long as I can remember.

I've checked Logitech's forums and I've done google and yahoo searches with no luck. In fact I only found one thread on some CS:S forum mentioning this problem with a few posters saying they had it too but there was no fix.

I guess the old mousefix.reg file that worked in XP no longer works, but I haven't tried it (it'd probably just break something else).

I'm curious as to how anyone is playing any competitive games in Vista with this crap turned on...?

You sure it's not that "Render X frames ahead" setting for you vid card? I think it defaults to 3 and I can really tell the difference between 3 and 2. I haven't adjusted it on my Vista install in awhile, and don't even have Rivatuner installed but maybe you should check that out.

Double check that you have 'Game detection' Enabled and 'Keep mouse acceleration off'. Also try reinstalling SetPoint if you've been changing registry options or using some of those 3rd party tools. My G7 seems to work fine with those settings, otherwise spin spin spin.

I recently upgraded to the new 2 button G5 mouse and noticed that Vista for some reason still has a control panel setting for the mouse that effects the G5 mouse independent of the Setpoint software. So, I turned off acceleration in the Vista mouse control panel and that did make things better. Have a look at that and see if that might be the problem.

That's what the problem is?! Wow..I wouldn't have guessed. That does make me think of a vista tweak I saw a while back though, diabling all unused HIDs in the device manager. he claimed it cleared up a lot of his problems.

Either way, glad you found the problem!

i'm not 100% positive, but i did uninstall G15 driver/sofware rebooted, pluged in an old MS wireless keyboard and played fear for over an hour and no problem.

In setpoint I had to turn on "Setpoint implementation" under speed and acceleration, then turn pointer acceleration off.

That seems to have gotten rid of it. I tried changing it form OS to setpoint implementation before but I guess it keeps track of the acceleration settings for each mode and I must have forgot to turn acceleration off again after changing it.

1 problem down, 40 more to go.

If I wasn't so damned picky I probably wouldn't even notice most of the "problems" my PC is having.
